摘要

A first coupling member 10 has a body 11 and an internal poppet 16. The exterior of the body 11 includes flats 30. A lug 31 is formed on one of the flats 30 during machining of the flats 30. A dust cover attached to the first coupling member 11 includes a cover portion 40 and a tether portion 41. The cover portion 40 protects an exterior surface 19 of the body, and the cover portion 40 to and tether portion 41 each protects one lateral side of the lug 31. The tether portion 41 includes an annular ring portion 43 disposed in an annular groove 25. A second embodiment 110 of the first coupling member is also disclosed.
